Need some advise and reassurance please

Thursday morning I woke up with my right boob hurting like hell, had full body aches, headache, fever chills the works, with a big area of the boob having a big red warm to touch area, Friday morning felt better now flu like symptoms but the boob still sore red and hard. Fast ward to today the redness is gone and the tenderness is pretty much gone and the area of being hard has gone down to only a small area, but I'm freaking out because the skin over the hard area is wedge shaped and the skin is raised up like inflamed looking and I have a slight burning sensation ever time baby feeds and last a lil while after and i feel pretty fine besides still feeling really ran down and tried but it has me worried sick to death. I believe that I have gotten the mastitis, i have never dealt with this before and don't know if it's normal. Has anyone dealt with this before and can give me some peace of mind please. Can mastitis cause inflammation and the lumpy part to still be there 4 days later after fever is gone? I'm really freaked out because I googled and I definitely shouldn't have due to I'm a worry wort in the first place. So please if any of you ladies have dealt with this I need some reassurance right about now before I go into a full blown panic attack. Sorry so long. TIA
